Technical points of breeding and fattening of hybrid cattle
The development of beef cattle production has excellent comprehensive economic benefits and broad market prospects. For the majority of farmers, the development of beef cattle production is a good way to make a fortune. To raise more beef cattle and good beef cattle, it is necessary to change concepts and change the past. The kind of traditional and backward extensive breeding methods, but the new scientific method of raising beef cattle. Hybrid cattle have the characteristics of fast growth, large size, good meat quality, and high feed remuneration. Therefore, the majority of farmers have recently developed beef cattle to breed hybrid cattle. The following briefly introduces the breeding and fattening techniques of hybrid cattle for your reference:
1. Change the concept, good breeding of cattle requires good laws. Change the traditional and backward extensive breeding methods in the past, and use new scientific methods of raising beef cattle.
2. In order to promote the development of the rumen, calves should eat green coarse fodder and concentrate early for feeding.
The calf suckling should not be less than 5 kilograms a day, otherwise the growth and development will be hindered. The local cattle breeds in our province will not produce high milk production. However, because of the larger body weight and faster weight gain, the milk production of hybrid calves is even more insufficient. For this reason, calves should eat green roughage and concentrate early to promote rumen development and supplement nutrients. In the current situation, weaning is generally adopted at the age of 6 months, and reared in groups after weaning.
3. Plant grass scientifically and learn how to store grass
Cattle are herbivores and should be based on roughage and supplemented by concentrate. However, farmers in mountainous areas have little high-quality green hay, which is not enough, and the nutrition of straw roughage is too poor, and the digestibility is low, which can only play a role in filling the stomach. Therefore, it is necessary to select the appropriate forage species for forage planting. Such as American dwarf elephant grass, flat ear hevida, Mexican corn, Guimu No. 1, ryegrass and so on. At the same time, we must learn the grass storage technology, and carry out ammoniating, silage, and micro-storage treatments. For example, after the ammoniated corn stalks, the nutritional value can be increased from 5% to 9%. The cattle love to eat, and the cattle's feed intake can be increased to 20%. , For example, after the ammoniated straw, the digestibility of organic matter can be increased by 19.7%, the digestibility of crude fiber can be increased by 22.8%, and the feed intake of cattle can be increased to 30%.
4. Management of fattening cattle.
The fattening calves are fed 3 times a day in the house, feeding the forage first, then the ingredients, and finally drinking water. Coarse materials should be unlimited, and the amount of fine materials should be added at 0.5-1% of body weight. Generally, drink water 1 hour after feeding. It is forbidden to feed iced feed and drink cold water. Drink warm water in cold winter. Wipe the cow body once a day to promote blood circulation, increase appetite, and keep the cow body hygienic. Feeding utensils should also be washed and disinfected frequently. Fattening cattle must do a good job of disease prevention and control on time, and often observe the cattle's feeding, drinking and ruminating conditions, and timely treatment if the condition is found. Fatten cattle 10-12 months of age with insect killer or levamisole deworming once. The oral dose of Chongbuxing is 0.1 grams per kilogram of body weight for each head; the oral dose of Levamisole is 8 mg per kilogram of body weight for each cow. At 12 months of age, use "artificial salt" once to invigorate the stomach, and the oral dose is 60-80 grams per cow.
Fifth, make full use of the slag feed. Farmers in mountainous areas have many distillers' grains, bean curd dregs, sugar dregs, and soy sauce dregs, with high yields. They are good feeds for cattle and far better than pigs and chickens. But the nutrition is not balanced, especially when fed alone, the effect is not good, and cattle are prone to digestive disorders and nutritional deficiencies. Only a reasonable combination can harvest good breeding and weight gain effects. You can also make some supplementary feeds with high sugar content and rich vitamins for feeding, and the fattening effect will be better. Such as saccharified feed, germinated feed and so on.
